Attempting to realize carbon neutrality in every sector of society has become an important issue relating to the mitigation of climate change. It is, however, difficult to achieve carbon neutrality in material industries, especially chemical and paper manufacturing. On the other hand, the waste sector is also making the necessary shift to a carbon-neutral system, with cost reduction being an important issue. Therefore, proposing a system that can solve the problems of both the waste sector and material industries at the same time is a possibility. It is also possible that combustible wastes which are difficult to recycle and are currently incinerated and used for power generation in each municipality, can be collected in petrochemical complexes where the waste can be efficiently used as a fuel to supply heat for their production processes. Since the energy density of waste is somewhat high, it is expected that the required long-distance transportation of waste is reasonable considering both the CO2 emission reduction effect and its economic merits. It is my hope that the proposed system will be introduced and established as a new structure that can bring about synergistic effects in terms of both the environment and the economy.
